Fix a bunch of issues related to edition and reply #5969

[ganfra]

This fixes #5969
It replaces this PR even if the fix is not the same.

The downside is, it doesn't fix the edition of markdown, but at least we can keep the permalink...

I tested the edition of a "reply to" message with permalink and user pills. This is working like a charm:
without the rich text editor:

with the rich text editor:

I tried using the RTE to edit a message in this order:

1. Text formatting enabled: the message was edited just fine.
2. Same message, text formatting disabled (but RTE enabled in labs):

I think the MD text should be displayed there instead of the HTML, and in any case the mx-reply should be gone.

@jmartinesp I understand your point, but I'm not sure we should spend more time on this edge case where the Text formatting is disabled between 2 editions of the same message. I will let you decide about this with the Android team.
I didn't reproduce this issue in Element-AndroidX, which is for me the most important.

[jmartinesp]

There is the issue mentioned above, but it was there before and will required a different fix than this, but other than that it LGTM, just a question about detecting the mx-reply tags.

[jmartinesp]

Could we get a </ mx-reply> tag, with one or several whitespaces?

[ganfra]

I hope not, I kept the same tags than before.

[ganfra]

Ok, lets iterate later with the other issues.

In Element Android v1.6.10 I cannot reply to any message. The option simply doesn't exist.
