Enable running `machete-status-branch hook` both in tests and the actual plugin on Windows

[Beniamin-Dolega]

testCommon/src/test/resources/common.sh:39 Make this four lines of code (40-43) work on windows.

Given that you @mkondratek will soon switch to Windows for a moment, this might be a good occasion to check. It'll be mostly a matter of making sure that com.virtuslab.gitmachete.backend.impl.hooks.StatusBranchHookExecutor#executeHookFor properly launches .git/hooks/machete-status/branch as a Bash script... TBD how to ensure that on Windows.

Actually, would be good to check how e.g. JGit launches git hooks: org.eclipse.jgit.hooks.GitHook#doRun seems a good place to start (org.eclipse.jgit.util.FS_Win32_Cygwin#runInShell FTW) — maybe actually delegating execution of hooks to JGit (via GitCoreRepository) would be the best solution here, to make both backendImpl:test and hooks in the actual execution of the plugin work.

[mkondratek]

The problem with the hook on windows comes from subprocess creation. There we need to run bash script but we do not know if the user actually uses some git bash (or any other tool enabling that).

Not a solution but I improved code and error handling a bit: https://github.com/VirtusLab/git-machete-intellij-plugin/pull/822
