Merge #12718: [Tests] Require exact match in assert_start_raises_init_eror (jnewbery)

fae1374 qa: Allow for partial_match when checking init error (MarcoFalke)
5812273 [Tests] Require exact match in assert_start_raises_init_eror() (John Newbery)
0ec08a6 [Tests] Move assert_start_raises_init_error method to TestNode (John Newbery)

Pull request description:

  Extracted from #12379, because the changes are important on their own.

  This allows for exact testing, since the match can be specified with a strict regex. Internal details (such as exact formatting of the error message) can still be fuzzed away by regex wildcards.
