Fix NPE when host has untagged images.

[kunickiaj]

When the docker host has untagged images the checkDiskSpace() method will throw a NullPointerException due to getRepoTags() returning null.

This simply adds a null check to avoid this situation.

Thanks - this looks good to me. Looks like Travis isn't merging in a fix on master for broken dependency shading; sorry about that.

I'm testing locally and expect to merge shortly.

I was about to report the same issue. So commenting here to make you aware that this is not singular.
Thanks for the fix @kunickiaj
