[BUG] The 'contains' operator throws RSOE when used with non-list field

[Marxsal]

Describe the bug

An RSOE is thrown when using 'contains' .

Expected behavior

Empty set

To Reproduce

Use the advanced search to create a filter like:

[all[tiddlers]contains:created[20250115]]

Instead of simply failing to find any matches, it throws a RSOE (Red screen of embarassment).

TiddlyWiki Configuration

v5.3.6

Uuups, This should have been catched by the tests.

There are 2 problems here.

1. There is no check if the list-variable exists
2. created is one of the tiddler fields that need to be treated in a special way. Internally they are stored as a js-date variable. For users they are strings.

PR is under way

@Marxsal There is an other problem. The created field will always be serialized like so: "20160204225047445" ... So a filter will need to match down to the millisecond. -- Your filter [all[tiddlers]contains:created[20250115]] will always return an empty list.
