Text to go in the release notes:
This fixes the cause of warning messages in the log files when the rental discount in the circulation rules has a blank value. Before this fix, multiple warning messages "[2021/07/28 12:11:25] [WARN] Argument "" isn't numeric in subtraction (-) at /kohadevbox/koha/C4/Circulation.pm line 3385." appeared in the log files. These warnings occurred for items checked out where they had rental charges and the rental discount value in the circulation rules was blank.

Description Nick Clemens (kidclamp) 2021-07-28 12:23:38 UTC 
If you set the rental discount field blank in circ rules it is stored as ""

Checkout an item:
[2021/07/28 12:11:25] [WARN] Argument "" isn't numeric in subtraction (-) at /kohadevbox/koha/C4/Circulation.pm line 3385.

Bug 28774: Don't store blank values for rental discount

This patch adds 'can_be_blank => 0' for the rentaldiscount rule to prevent
storing blank values in the database

Additionally, if there is no charge we do not need to check for a discount
and can simply return

To test:
1 - Set rental discount to "" to a rule in circulation rules
2 - Checkout an item that will follow this rule
3 - Check the intranet log:
    [WARN] Argument "" isn't numeric in subtraction (-) at /kohadevbox/koha/C4/Circulation.pm line 3385.
4 - Apply patch and restart all
5 - Update database
6 - Set the rule to "" again
7 - Check the DB, no rule is stored
    SELECT * FROM circulation_rules WHERE rule_name = 'rentaldiscount';
8 - Checkout the item again
9 - No warns in log
