Fix crash when using webconsole

Closes #18856
Additional changes from #18761

Fixes a crash when using Metasploit's webconsole

Verification

Ensure that the user message notification still works when the smb session flag is enabled:

msf6 auxiliary(scanner/mysql/mysql_hashdump) > use auxiliary/scanner/smb/smb_login
[*] New in Metasploit 6.4 - The CreateSession option within this module can open an interactive session
msf6 auxiliary(scanner/smb/smb_login) >

Looks like it's working for me

msf6 auxiliary(scanner/smb/smb_enumshares) > use smb_login
