changing name of Menu changes name of Category and vice versa

[kris-o3world]

to replicate:

1. Appearance -> Menus
2. create a Menu (ex. "My Menu")
3. add a Category as the first item in that Menu (ex. a category named "Learn")
4. rename the Menu to something else (ex. "Main")
5. Posts -> Categories
6. the name of your Category ("Learn") is now the name of the Menu ("Main")
7. rename the Category ("Learn")
8. back to Appearance -> Menus
9. the name of your Menu is now the name of your Category ("Learn")

this has been reported to happen with Tags as well, see that ticket: #16936

it is interesting to note that this does Not happen if the first item in your Menu is a Page.

i take that back... even when the first item is Not a category, the first Category wordpress does "find", gets renamed.
