`minimesos up` crashes when local docker contains image with no tags.

[maasg]

The minimesos up command will fail with the following exception when the local docker registry contains images with no tags (denoted as "" on the docker cli)

Exception:

Example docker images listing that causes the failure:

Suspected cause in the code:

com.containersol.minimesos.container.AbstractContainer#223
  for (String repoTag : image.getRepoTags()) {

Thanks for the report @maasg ! We'll fix this asap, looks like an easy one.

Thanks for reporting @maasg!

I've just installed the latest version (0.13.0) and getting the exact same problem:

$ minimesos up # Created minimesos directory at /Users/radek/Downloads/minimesos-0.13.0/bin/.minimesos. Failed to run command 'up'. null

@maasg did the fix work for you? :D

@radek1st I just had the same issue, and resolved it by removing any images locally that didn't have a tag.
