Overwriting bookmarked query causes PHP Fatal error

[TheWatcher]

Describe the bug

When "Replace existing bookmark of same name" is selected when running a SQL query, the query fails with an "Error in processing request" popup. When looking in the server logs, I have the error:

PHP Fatal error:  Uncaught TypeError: Argument 5 passed to PhpMyAdmin\\Sql::storeTheQueryAsBookmark() must be of the type bool or null, string given, 
called in [path removed]/phpMyAdmin-5.0.2-english/import.php on line 772 and defined in [path 
removed]/phpMyAdmin-5.0.2-english/libraries/classes/Sql.php:903\nStack trace:\n#0 [path removed]/phpMyAdmin-5.0.2-english/import.php(772): PhpMyAdmin\\Sql-
>storeTheQueryAsBookmark('aviary', 'chris', 'SELECT * FROM `...', 'testing1', 'true')\n#1 {main} 
thrown in [path removed]/phpMyAdmin-5.0.2-english/libraries/classes/Sql.php on line 903

To Reproduce

Steps to reproduce the behavior:

1. Go to the SQL tab for a table in a database
2. Enter a query
3. Enter the name of a previously bookmarked query in the "Bookmark this SQL query:" box
4. Tick the "Replace existing bookmark of same name"
5. Click "Go"
6. 500 "Error in processing request" popup appears and the above error is logged

Expected behavior

Query run, and bookmarked SQL query updated.
