Only cancel bonding if pair button is not pressed

aosp/2093046 cancels bonding unconditionally in onDestroy(), this
results in the user not being able to pair when the pair button is
pressed because onDestroy() is also called in that case.

Only cancel bonding if the user did not press the pair button.

Bug: 231554812
Test: Changed settings app is able to scan after dismissing the dialog
and is also able to pair when the pair button is pressed
