ugly 'no such file or directory' message when setting terraform version for the first time

Hello,

It's a minor bug and does not affect how tfenv works, but still - looks odd.

When you do not have any version installed and you type tfenv install - it downloads you latest terraform. However - it does not set it as default. you need to use tfenv use {version number} or just tfenv use (second defaults to latest).

However, during that commands (tfenv use) I get following message:

root@18f0602938de:/# tfenv install

cat: /usr/local/lib/tfenv/version: No such file or directory
Switching default version to v1.1.2

The part cat: /usr/local/lib/tfenv/version: No such file or directory is very odd - I think we should test for existence of that file and not let bash output that message.

Additionally, perhaps if there is no version installed, tfenv install could automatically set that version as default?

I can +1 this. To get around this, after installing terraform using tfenv, I echo "$version" > path/to/tfenv/version. In my case, that file doesn't actually exist and it does affect whether terraform can execute.
