It doesn't get translated in the TS build, for one.

Script I used:

```python
import os

for (dirpath, dirnames, filenames) in os.walk('.'):
    if '.git' in dirpath:
        continue
    if 'node_modules' in dirpath:
        continue
    if 'dist' in dirpath:
        continue
    if 'types' in dirpath:
        continue
    for filename in filenames:
        path = os.path.join(dirpath, filename)
        if not path.endswith('.js') and not path.endswith('.ts'):
            continue
        #print(path)
        with open(path, 'r+') as f:
            #print(f)
            data = f.read()
            if '__filename' in data:
                p, ext = os.path.splitext(path)
                txt = f"'{p[2:]}'"
                print(txt)
                data = data.replace('__filename', txt)  # Assign the result back to data
                f.seek(0)
                f.write(data)
                f.truncate()
```

If guest authenticates in meeting to become a moderator and creates a breakout room, was not inviting jicofo and fails to join breakout room.
Fixes jitsi/jitsi-meet#15024.

This fixes changes from 1b5830f1bd

Fixes jitsi/jitsi-meet#13455.

It's not necessary to perform a full join, sending a conference IQ is
enough.

This functionality is being brought back for apps
that use ljm for its prosody logic but not for
video conferencing, ie Jitsi-Meet Spot. The desired
use is for Spot-TVs to be identifiable by their
jid alone and for the resource to be the part
that identifies them.

Include XMPP user's credentials in the
CONNECTION_FAILED/PASSWORD_REQUIRED error event.

With JitsiAuthConnection the API consumer has to:
1. JitsiConference.createAuthenticationConnection,
2. JitsiAuthConnecition.authenticateAndUpgradeRole,
3. Wait on the Promise of 2,
4. Maybe cancel the JitsiAuthConnection of 1.

With authenticateAndUpgradeRole the API consumer has to:
1. JitsiConference.authenticateAndUpgradeRole,
2. Wait on the thenableWithCancel of 1.
3. Maybe cancel the thenableWithCancel of 1.
