fix(ext/flash): graceful server startup/shutdown with unsettled promises in mind (#16616)

Browse source 
This PR resets the revert commit made by #16610, bringing back #16383
which attempts to fix the issue happening when we use the flash server
with `--watch` option enabled.
Also, some code changes are made to pass the regression test added in
#16610.
