Cannot create Stash with same name as existing Stash.

For quick stashes, I often create stashes with common names, such as "stash".

When I get a name collision (a stash called "stash" already exists), the SourceTree prompt says:

> A stash with this name already exists.

> Do you want to create a new stash with the same name? Your existing stash will not be overwritten.

See pics.

I do want to create a NEW stash with the SAME NAME. So I click "OK".

EXPECTED:

• The prompt behaves as it says it will. Namely:
• Creates a new stash with the same name.
• The existing stash named "stash" is not deleted
• Changes are stashed. Working copy is clean.

ACTUAL

• Creation of the stash fails.
• New stash "stash" is not created.
• My working copy is still there. Changes are not stashed.
• I'm forced to type a unique name, rather than "stash".

This is a regression in SourceTree 2. In SourceTree 1, I was able to create multiple stashes with the same name.
