Detailed Description

set_source_string() is deprecated in favour of set_source(PriceSource.*),
but while it exists it must fail loud on an unrecognized source string
instead of silently leaving the source unchanged (the C setter no-ops).
These tests ignore the DeprecationWarning and check the guard behaviour;
the warning itself is covered by test_emits_deprecation_warning.
