Added a check for empty email address so that if the adhoc task
for sending email notifcation to users for forum update fails
because of empty email address an exception is not thrown as
the exception was causing the the task for user with empty email
address to keep requeuing again and again after failing.
Wrote two test cases for testing if the fix has now prevented
the task for empty email address to be requeued after failing
and to test that if its still requeuing for other cases when
the adhoc task fails for some other reason in this cause we are
testing for bounce threshold.
In PHP 8.2 and later, setting a value to an undeclared class property is
deprecated and emits a deprecation notice.
So we need to add missing class properties that still need to be declared.
Create a new profile field type, move all existing content of the fields
'icq', 'skype', 'aim', 'yahoo', 'msn' and 'url' in the mdl_user table to
theses new profile fields if needed.
