GitBuddy hangs when no SSH passphrase was provided to git

[MaxDesiatov]

In repositories with SSH authentication GitBuddy hangs at the "Fetching tags" stage. It attempts to run git fetch --tags origin --no-recurse-submodules -q, but this command requires an SSH key passphrase from the standard input stream to proceed for some remotes. Since GitBuddy doesn't provide it, the whole GitBuddy process hangs with no visible feedback.
