Exception when MQTT and KeyBLE credentials were not yet set

[KlausMu]

In file "src/main.cpp" I had to change line
if (do_open || do_lock || do_unlock || do_status || do_toggle || do_pair)
to
if ((KeyBLEConfigured) && (do_open || do_lock || do_unlock || do_status || do_toggle || do_pair))
otherwise I got "Guru Meditation Error: Core 1 panic'ed (StoreProhibited). Exception was unhandled." when MQTT and KeyBLE credentials were not yet set because
eQ3* keyble;
was accessed uninitialized.
