tests: add tests for showing stack when merge is involved
This patch adds tests of showing stack when merges are involved. This will help
us in changing the behaviour and realising that in later patches.

hg topics [TOPIC]
View current topic, set current topic, change topic for a set of revisions, or
see all topics.
Clear topic on existing topiced revisions:
'hg topic --rev <related revset> --clear'
Change topic on some revisions:
'hg topic <newtopicname> --rev <related revset>'
Clear current topic:
'hg topic --clear'
Set current topic:
'hg topic <topicname>'
List of topics:
'hg topics'
List of topics with their last touched time sorted according to it:
'hg topic --age'
The active topic (if any) will be prepended with a "*".
The '--current' flag helps to take active topic into account. For example,
if you want to set the topic on all the draft changesets to the active
topic, you can do: 'hg topic -r "draft()" --current'
The --verbose version of this command display various information on the
state of each topic.
options ([+] can be repeated):
--clear clear active topic if any
-r --rev REV [+] revset of existing revisions
-l --list show the stack of changeset in the topic
--age show when you last touched the topics
--current display the current topic only
(some details hidden, use --verbose to show complete help)
$ hg topics
Test topics interaction with evolution:
$ hg topics --config experimental.evolution=
