Opt-in user setting Boolean value incorrectly saved with quotation marks

Evergreen 2.8.1
OpenSRF 2.4

In our system, we have action triggers for circulation notice emails that use the following opt-in setting:

name: opac.default_circ_notices_enabled
label: Receive Overdue and Courtesy Emails
datatype: bool
reg_default: true

When registering a patron in the staff client, the registration interface automatically includes a checkbox "Receive Overdue and Courtesy Emails" which is checked by default. This is the desired behavior. However, when saving a new patron record, the value for that user setting is saved in the database as '"true"' (with double quotes), instead of 'true' (no quotes). Subsequently, when OpenILS::Application::Trigger checks the new patron's opt-in setting, it apparently looks for an exact match; in this case, it will conclude that the patron does NOT have this setting set to 'true'. As a result, no circ notice events are generated for this patron, and they receive no circ notice emails, even though the correct box has been checked in the patron editor.

The solution would be to (1) save the user's opt-in setting value without double quotes, since it's a Boolean value, and/or (2) ignore quotes when checking the value during event generation.
