Double-clicking in rename input acts like double-clicking file normally

[peterflynn]

1. Select an item in the file tree
2. Right-click > Rename
3. Double-click inside the text field

Result: the rename is committed (not canceled), and the file is added to the working set.

Expected: selects word in text field, just like double-clicking in other text fields. Rename mode remains active and file isn't added to working set.

This repros in master, so it's not related to rename-on-click (#2412)
