Update VersionParser to deal with empty dokku versions #230

Closed jvanbaarsen closed 6 years ago

jvanbaarsen commented 6 years ago

When there s no Dokku installed on a server, we get a Command not found back. When we store that in our Dokku version field and later check it against the VersionParser it will blow up.

I updated the VersionParser gem to prevent this issue.

fixes: #229
