Tests: Pad incrementors used in factories with leading zeros to make sure MySQL sorting works as expected.

Previously, tests could create sequential objects with names like Term 99, Term 100, which by default would be returned in reverse order when sorted by name alphabetically, causing seemingly random test failures that are extremely hard to debug.

See #48145.
