Fixed: Play Store reported a crash error when closing the tabs.

[MohitMaliFtechiz]

Fixes #3790

This error was occurring due to the user frequently clicking the close icon of the same tab, in this situation first click closes the tab, and the second immediate click again triggers the closeTab function but recyclerView does not have the valid view for this position because it is in removing process so this makes this view invalid and recyclerView returns the -1 index for invalid views. So this was the reason for this issue, to address this issue we have added a check in our closeTab method if the incoming index is -1 then it will not execute the further code.

• Enhanced the Tab closed snackBar behavior. Now, when the user clicks the UNDO button to restore a tab, we disable the snackBar's "UNDO" button to prevent subsequent clicks. This prevents the addition of multiple tabs if the UNDO button is clicked multiple times, as this type of restored tab leads to unexpected behavior see below video.
