GMod prerelease: incoming cmds no longer get processed if serversecure is loaded

[Python1320]

Repro:

1. Start srcds in prerelease
2. load serversecure
3. join
4. try to say anything (lets you join all the way ingame somehow though)

Untested with serversecure alone, narrowing down now.
Vanilla server with serversecure alone (loaded during runtime with manual call to serversecure.RefreshInfoCache()):

• if already ingame and loading serversecure: nothing seems to break
• if trying to rejoin: stuck at "Clientside Lua startup!"
