Fix extra padding of recyclerview after renamed the file

When rename and ime is shown, it will trigger OnApplyWindowInsets,
so it will change the bottom inset and update the padding by our
implementation. However, it will not recover after ime dismiss due
to timing issue.

Use PreDrawListener in DirectoryFragment to update correct padding
after OnApplyWindowInsets.
