fix: Merging results for non legacy Android run

[piotradamczyk5]

Fixes #2143

Test Plan

How do we know the code works?

Results are merged properly as per discussion.

1. Run flank with flank-multiple-success.yml config
2. Check that JUnitReport.xml has grouped testsuite node by name

Before:

<?xml version='1.0' encoding='UTF-8' ?>
<testsuites>
  <testsuite name="NexusLowRes-28-en-portrait" tests="8" failures="0" flakes="0" errors="0" skipped="0" time="3.364" timestamp="2021-08-24T20:39:40" hostname="localhost">
    ...
  </testsuite>
  <testsuite name="NexusLowRes-28-en-portrait" tests="12" failures="0" flakes="0" errors="0" skipped="0" time="3.853" timestamp="2021-08-24T20:39:40" hostname="localhost">
    ...
  </testsuite>
  <testsuite name="junit-ignored" tests="4" failures="0" errors="0" skipped="4" time="0.0" timestamp="2021-08-24T20:40:30" hostname="localhost">
    ...
  </testsuite>
</testsuites>

After:

<?xml version='1.0' encoding='UTF-8' ?>
<testsuites>
  <testsuite name="NexusLowRes-28-en-portrait#" tests="20" failures="0" errors="0" skipped="0" time="6.894" timestamp="2021-08-24T20:47:28" hostname="localhost">
    ...
  </testsuite>
  <testsuite name="junit-ignored" tests="4" failures="0" errors="0" skipped="4" time="0.0" timestamp="2021-08-24T20:48:17" hostname="localhost">
  ...
  </testsuite>
</testsuites>
