- Previus version was still incorrect as it ignored cases where GitLab would
  be installed in a custom location.
- This assumes that if this method can be calle, web_url will return a valid
  URL.

- This should work correctly in all cases now.
- Added a new project method that returns the web url for a project without
  the scheme prefix.

Be default it sorts by name now
Respect filters like scope, label, visibility when do sort or another
filter

GITLAB-1457 (GITLAB-836)

Change-Id: If8e2474bc6908accca51f395f58937687f101b58

Fix error described in https://github.com/gitlabhq/gitlabhq/issues/5185

Labels are saved in the database with the case they were originally created with.
Before this change if a user created a label with the same text but different case
the label would use the original case and no new label would be created in the
database. With this change, labels are now case-sensitive.

Steps to test:

1. Before this change, create a new issue with a new label "FIxMe"
2. Edit the issue and change the label to "FixMe"
3. Note that the label reverted to "FIxMe"
4. Apply this change
5. Edit the issue again and change the label to "FixMe"
Note that the new case was preserved. If you also look in the database in the "tags" table you will see that both labels are present - "FIxMe" and "FixMe".

Added test for the FlowdockService.

Before we have only owner_id to determine group owner
With multiple owners per group we should get rid of owner_id in group.
So from now @group.owner will always be nil but
@group.owners return an actual array of users who can admin this group
