fix(sessions): re-detect sessions in read after session is sourced

[abeldekat]

• I have read CONTRIBUTING.md
• I have read CODE_OF_CONDUCT.md

After reading a session, the local session stored in MiniSessions.detected can be stale.

Resolve #2260

[abeldekat]

While reading source and test code, I found some spelling errors where "is" should be changed in "are":

line 137
--- beforehand for unsaved listed buffers and stops if there is any.
line 158
return H.message('There is no detected sessions. Change configuration and rerun MiniSessions.setup().')
line 291
H.error('There is no detected sessions. Change configuration and rerun MiniSessions.setup().')

Spelling test:
line 333:
expect.match(get_latest_message(), '%(mini%.sessions%) There is no detected sessions')
line 761:
'%(mini%.sessions%) There is no detected sessions'
line 1005:
T['get_latest()']['works if there is no detected sessions'] = function()

Thanks for the PR!

I didn't think about that, but It indeed makes sense to test different kind of interactions between what was before and what is after read regarding local session. Does the suggestion test sound reasonable?

Could you please add another docs(sessions): fix "is/are" typos commit here that addresses all found problems (including tests)? Don't forget to regenerate help files.

Also, please adjust the commit message to be fix(sessions) and have Resolve #2260 as part of the message.

Thanks again for the PR! Everything looks good now!
