Editing message forgets line breaks and markdown

[Porrumentzio]

Describe the bug
When sending a message with line breaks and/or markdown markup and taping the edit option, those line breaks and markdown markups disappear, resulting in very odd messages.

To Reproduce
Steps to reproduce the behavior:

1. Go to a sent message
2. Click on "edit"
3. The line breaks and markdown have disappeared

Expected behavior
When editing a message, all of its line breaks and markdown should stay in a editing mode (should appear the *, _, ` and so on).
The line breaks should also stay.

Screenshots
Here can be seen the message with markdown (also line breaks, but that's not so evident)

Here can be seen how, when editing, the line breaks and markdown is lost.

Seems to be related to #853 and #1982

Will this also correct the line breaks issue?

This one could actually be closed by #2002, please reopen it if it is not the case (to check on Element Android v1.0.6)

Hi! I'm on Element Android 1.0.7 and line breaks still get forgotten after editing.
