Fixes #520

Fixes #525

The message input entry was being focused only in folded mode.
Fix it to work on non-folded mode too

Fixes #519

If the file is prefixed with mxc://, create the
http url and use it

And replace chatty-chat instances with chatty-pp-chat

On first call, the username is created, but returns "".
Fix to return username on first call too.

Fixes #515

strcasestr is locale sensitive and may not match if the string
is different from current locale.

Fixes https://gitlab.com/mobian1/issues/-/issues/338

We were assigning the result to a GObject variable, but in fact the result
is a JsonObject.  Fix it, and fix leaking the memory

We were creating a copy of the username for every call and never freed.

Without being able to rely on the schema name for the lookup,
we need a different attribute.

This is a hack we can use as long as there is only one protocol (or we would
need to call this multiple times for each protocol, which would also be doable).

With the last commit and without this one we get warnings from chatty:

`WARNING: secret_service_search: must specify at least one attribute to match`

When a keyring is cold (unlocked) the schema is set as
"org.freedesktop.Secret.Generic". If we require the name to strictly match
while searching we won't ever get a match.

See https://gitlab.gnome.org/GNOME/gnome-keyring/-/issues/89 and
https://gitlab.gnome.org/GNOME/libsecret/-/issues/7 for more information.

Closes #512

This can help improve debug experience and catch memory bugs better.

So that the window won't grow beyond the display size

Fixes #506

Otherwise the following request will simply be not performed
as the cancellable is now in cancelled state

Which uses less memory

All we do is to save the error and then delete it, never use.
