Removed hard-coded references to the 'checked_out' database column and replaced them with variables containing the column alias, obtained through a $this->getColumnAlias() call. Now, the 'checked_out' column references mirror the 'published' column references in their respect for column aliasing.

Pull Request for Issue #42688 .

Summary of Changes

Removed hard-coded references to the 'checked_out' database column and replaced them with variables containing the column alias, obtained through a $this->getColumnAlias() call. Now, the 'checked_out' column references mirror the 'published' column references in their respect for column aliasing. Also made sure the '=' operators lined up nicely in the variable declaration/initialization lines while I was at it.

Testing Instructions

Change the published state of one or more items whose data are stored in a nested table, i.e. the Tags component to ensure the change did not break existing functionality. To verify new support for aliasing, instantiate the class and call the publish() method from a client that uses an alias for the 'checked_out' column.

Actual result BEFORE applying this Pull Request

Attempting to change the published state of an item in a custom admin list view failed with error message, "Unknown column 'checked_out' in 'where clause'". The database column was properly aliased in the table's __construct() method with the following code:

$this->setColumnAlias('checked_out', 'checked_out_user_id');

Expected result AFTER applying this Pull Request

Attempting to change the published state of an item in a custom admin list view succeeds.
