[FIX] web: no more double discard dialog

This issue only occurred in community.
Steps to produce:
1) Create/Edit any record.
2) Change the menu using menu switcher
3) You will get the discard dialog at the instance and after some
   time it will also display another duplicate discard dialog.

So, we have one extra redundant discard dialog on menu switching.
It is working fine when we have dirty form and then click on the
breadcrumb or click on any internal child menu.
