Minor fix to the notification checks

To ensure that we don't fail if we have more permissions than requested
e-mission/e-mission-docs#722 (comment)

Without this fix, having sound enabled for app notifications would cause the
checks to fail to fail, since the requested flags = 5 and the actual flags = 7

With this fix, we bitwise and the two values to remove the excess permissions.
7 (111) & 5 (101) = 101 = 5 = requested permissions
