Refactor destroy controller (#17194)

* Remove redundant conditions

They were always true. First, the variable is set to -1.
If the variable is -1, then set it to Message.
If the variable is Message then set the JSON array. All of this is
redundant.

* $sqlQuery is not used anywhere

* Enforce $selected to be an array

I can't remove it as it is a global. Previously, it was set to a POST
variable. Since we validate that the variable is set and is not null,
we can use the value from $params. If we validate that it's also an
array we can replace for loop with foreach.
There is no passing by reference, so this change should be safe.

* Replace $rebuildDatabaseList with input validation

The validation message says 'No databases selected.' so I assume that
we should check that we actually got at least one entry in the list.
If that is true, then the $rebuildDatabaseList is not needed and the
condition redundant.

* drop_selected_dbs is always set and is redundant

I am not sure if this is necessary. The AJAX request sends a value of "1"
but the code doesn't really do anything with it other than checking if
it is actually set. Is there some other path possible?

* Flatten the array with a single element

* Remove redundant isset

The variable is set, so !isset === is_null. Why check for null if we can
check just for !is_array.
