Bug 1613394 [wpt PR 21600] - Replace some "promise_rejects(t, 'SomeDOMError', stuff)" calls with p…, a=testonly

Automatic update from web-platform-tests
Replace some "promise_rejects(t, 'SomeDOMError', stuff)" calls with promise_rejects_dom.

This diff was generated by running:

find . -type f -print0 | xargs -0 perl -pi -e "BEGIN { \$/ = undef; } s/promise_rejects\(([ \n]*[a-zA-Z_]+[ \n]*,[ \n]*)([\"'][A-Za-z_]*[\"']) *(, *.)/promise_rejects_dom(\1\2\3/gs"

in bash (doesn't work in tcsh, due to the $ inside "").
