I noticed that you can click the Abort button (during a rebase conflict) more than once, which leads to a A lock file already exists in the repository, which blocks this operation from completing.) error surfacing. Perhaps we need to disable it, although I am have no strong feels on this bug as it is unlikely to happen and the recovery is easy.

Repro:

• pull up Rebase conflict
• double or triple-click Abort button

Tried to repro it on merge conflict flow, but could not.
