Title: [2.0] Add check to Store::unlock to ensure file exists

This is the 2.0 version of #5375. Sorry if this is the wrong way to do it, but I thought it would be annoying for the core team to merge two different versions and since this is a bug fix I assume it's got to go into 2.0.

I won't repeat the summary here. Please see #5375 for it.
