DEV: Improve test coverage of themes:update rake task (#26764)

Browse Source 
This commit adds a test to ensure that settings for a theme are retained
even if saving a theme setting after a theme setting migration fails.
Prior to the fix introduced in 35bc27a36d,
failing to save the new settings will actually cause some or all of the
theme's setting to be lost.
