Update TestPlayerRunHelper to fail on non-fatal errors by default

Also introduce a fluent API that allows callers to ignore non-fatal
errors (while avoiding adding boolean overloads for every method).

**Most** tests want to fail on non-fatal errors (since they likely
indicate user-visible issues like codec errors etc), only tests
explicitly testing fallback in error scenarios should want to ignore
them.

Before this change there were a few `playUntilXXX` methods. These can
now all be triggered via `play(player).untilXXX`, which means
effectively every 'until' condition is available in a 'play until'
variant that calls `play` just before waiting for the condition.
