Location of page should be transformed following name strategy in rename UI

This ticket is separate from the one with the Validation Enabled.

I reproduced the issue on a fresh 17.10.10, with an Advanced user:

1. Selected the Preformatted names without special characters as a Name strategy , Transform names automatically - Enabled, Validate names before saving - Disabled.
2. I created a page with the name Test^&*A and the saved name was Test-A. It respected the chosen name strategy.
3. I renamed the page by expanding the New location and replacing the Name field from Test-A into Test$%#B
Expected result: a name respecting the name strategy
Actual result: Test%24%25%23B, thus the name strategy was not kept.
