evolve: strip the extra obsmarkers if any on `hg evolve --abort`
Previous patches started storing some obsmarkers which needs to stripped during
`evolve --abort` which can't be stripped by stripping the new evolved changesets
because they point to a node which existed before the evolution was performed.
This patch adds logic to strip those obsmarkers by finding their indices in the
obsstore and then stripping them.
