Merge #6329

6329: Stop printing “failed to update” message when changing sources r=segiddins a=segiddins

### What was the end-user problem that led to this PR?

The problem was `bundle update` shows incorrect message when updating git gems

Closes #6325 

### What was your diagnosis of the problem?

My diagnosis was we need to check if the source has changed

### What is your fix for the problem, implemented in this PR?

My fix only prints the message when the source has not changed

Note that is does not yet fix the "updated the git sha" case, since the locked spec and the new spec actually share the same source object!
