coala requires new version of git-url-parse

Travis CI fails as coala requires use of latest version of git-url-parse (1.2.0) but version 1.1.0 is used.

[Error as shown here:](https://travis-ci.org/coala/community/jobs/490882763#L1096)

```
[ERROR][07:14:47] There is a conflict in the version of a dependency you have installed and the requirements of coala. This may be resolved by creating a separate virtual environment for coala or running `pip3 install "git-url-parse~=1.1.0"`. Be aware that the latter solution might break other python packages that depend on the currently installed version.
```

Probably the new version doesn't have much change to break other things.
