stash hook to prevent unpushed submodules

[Robbin Bonthond]

We use https://bitbucket.org/atlassianlabs/bitbucket-submodule-safe-hook heavily to prevent people from pushing a master when they haven't pushed changed submodules yet. 

Unfortunately it seems this hook has stopped working in bitbucket-server 4.14.5 and git 2.11.1, all pushes are now rejected.

Is there someone with enough java knowledge to see if this can be fixed somehow?

this seemed related to upgrading from git 2.10.0 to git 2.11.1, downgrading git makes these hooks working again.
