tests: add a test demonstarting lose of phase in `hg evolve`
This patch adds a new test file which demonstrates the lose of phase information
when hg evolve command runs into conflict. This is algo bug5720. The upcoming
patch will fix it.
A new test file is added as existing test files serve their own purpose and are
already cluttered.
