Dip does not wrap an actual container command in quotes on Ubuntu

[snthpr1d3]

First of all, thank you for the really great, useful and handy tool. I apologize in advance for possible grammar mistakes. Also, I assume I might misunderstand the actual reason of the issue.

Describe the bug It's impossible to use a container application with arguments on Ubuntu and therefore it's impossible to use advanced shell constructions.

To Reproduce Steps to reproduce the behavior:

1. Create any folder, e.g. /tmp/test_project
2. Create the dip.yml config file in the folder:

   
   version: '2'

compose: files:

• docker-compose.yml

  interaction: bash: service: test command: /bin/sh

provision:

• dip bash -c 'if [[ true ]]; then echo works; fi'

  
  3. Create the `docker-compose.yml` config file in the folder:
  ```yaml
  version: '3.5'

services: test: image: alpine command: tail -f /dev/null

4. Run command `dip provision` or `dip bash -c 'if [[ true ]]; then echo works; fi'` from the folder.
4. See the error

sh: -c: line 1: syntax error near unexpected token then' sh: -c: line 1:docker-compose --file /home/snthpr1d3/work/dip_bug/docker-compose.yml run --rm test /bin/sh -c if [[ true ]]; then echo works; fi' ERROR: Command 'dip bash -c 'if [[ true ]]; then echo works; fi'' executed with error

**Expected behavior**
Performs the shell command correctly and prints "works" as on MacOS environment.

**Context (please complete the following information):**
 - OS: Ubuntu 21.04
 - Version 7.1.0

**Additional context**
Don't reproduce on MacOS environment.

As you can see the `dip bash -c 'if [[ true ]]; then echo works; fi` sample command transcripts into 

```docker-compose --file /home/snthpr1d3/work/dip_bug/docker-compose.yml run --rm test /bin/sh -c if [[ true ]]; then echo works; fi```

which is evidently requires quotes to surround the arguments like this

```docker-compose --file /home/snthpr1d3/work/dip_bug/docker-compose.yml run --rm test /bin/sh -c 'if [[ true ]]; then echo works; fi'```

as it was in the original config file: `dip bash -c  'if [[ true ]]; then echo works; fi'`

As I mentioned before, works correctly on MacOS.

Hi! I'll see about this bug this week.

[snthpr1d3]

I'm sorry for the misinformation, it turned out that behaviour does not depend on OS, it depends on the actual version of the gem. I got 6.1.0 on MacOS, and 7.1.0 on the linux environment. Tried out 7.1.0 on MacOS and got the same issue, then tried out 6.1.0 on linux and it worked.

@snthpr1d3 please try the new version
