Selected repo box position

[dimateos]

Currently selected repo IMO is more frequently used than "Configure...", so it could positioned first (left-most) in the top-bar.

Not very important, and quite subjective! I usually open specific repos from the "source control" views.

But wanted to mention it as due to https://github.com/phil294/GitLG/issues/152 I had to use it a lot to navigate multiple repos and found its position a bit unintuitive (position depends on window width etc).

Also wanted to mention it because: Maybe that position could be better suited for a potential branch-filter https://github.com/phil294/GitLG/issues/132 if you decide to implement it using a combo-box
