Change Bitbucket repository naming back

[langecode]

Clear and concise description of the problem

The Bitbucket repository naming was changed to accomodate the hardcoded requirement that "fullname" is always <owner>/<name>

Suggested solution

Naming scheme should be changed back t0

FullName:      fmt.Sprintf("%s/%s", from.Project.Name, from.Name)

as this is the most human-readable name.
