Remove --frozen-lockfile from dummy app install after yalc

The yalc workflow modifies yarn.lock when adding packages, so we cannot
use --frozen-lockfile after yalc has run. Keep --ignore-scripts to skip
the preinstall hook (since yalc already ran in the previous step).

This allows the install to succeed after yalc has modified the lockfile.
