test(e2e, android): Java gives you path in /data/user/0, use it to pull device coverage file

it is apparently a symbolic link to /data/data per docs, but in practice after Java dumped the file
there, adb could not see it. Java dumped it to /data/data locally but /data/user/0 in CI which was also odd

Also sleep a moment to let the app quiet down and dump the report
