vim-patch:9.1.1938: tests: excessive wait in Test_matchfuzzy_initialized

Problem:  tests: excessive wait in Test_matchfuzzy_initialized
Solution: Use term_wait() instead of the TermWait() wrapper
          (Corey Hickey)

Test_matchfuzzy_initialized is a terminal test, which are specified to be
"flaky" and automatically retried. The TermWait wrapper multiplies the
specified wait time by higher values for later retries, maxing out at
10x the specified value. This makes tries vim/vim#3 to vim/vim#6 sleep for 20 seconds
each, which makes the test very slow to work with. The specified intent
of the test (as noted in a comment eight lines above here) is to
sleep for 2s.
