Parsing of patp breaks for the rest of the message if a malformed patp is found

[lycurgus]

Describe the bug Typing text that looks like patp but isn't, breaks subsequent patp parsing in the message. E.g. the content:

~sampel-palnet ~sampel-notvalid ~sampel-sampel

will only render the first patp as a link/mention.

Screenshot:

To Reproduce Steps to reproduce the behavior:

1. Go to a group chat
2. Send a message like the above
3. Note that mentions after a malformed one do not parse/render

Expected behavior Parsing should resume after a failed patp parse
