Fix: resolve SSH url for git menu
Created by: abeatrix
This PR is to address the issue stated in https://github.com/sourcegraph/sourcegraph-jetbrains/issues/25
The Open in Sourcegraph from the git menu feature is currently working for projects that are using HTTP as their remote URL, but not for projects that are using SSH due to the command we run to get the URI. This fix is to turn URL that starts with git
into HTTPS format in the url builder function for git menu.
Removed utm tags to address https://github.com/sourcegraph/sourcegraph-jetbrains/issues/16 Enforce defaultBranch even if it does not exist in origin remote to address https://github.com/sourcegraph/sourcegraph-jetbrains/issues/15
