7f72840c36 Streams: fix xreadGetKeys() for correctness. 
The old version could not handle the fact that "STREAMS" is a valid key
name for streams. Now we really try to parse the command like the
command implementation would do.

Related to #5028 and 4857.

b686b085ed Fix getKeysUsingCommandTable() in the case of nagative arity. 
This fixes a crash with Redis Cluster when OBJECT is mis-used, because
getKeysUsingCommandTable() will call serverPanic() detecting we are
accessing an invalid argument in the case "OBJECT foo" is called.

This bug was introduced when OBJECT HELP was introduced, because the key
argument is set fixed at index 2 in the command table, however now
OBJECT may be called with an insufficient number of arguments to extract
the key.

The "Right Thing" would be to have a specific function to extract keys
from the OBJECT command, however this is kinda of an overkill, so I
preferred to make getKeysUsingCommandTable() more robust and just return
no keys when it's not possible to honor the command table, because new
commands are often added and also there are a number with an HELP
subcommand violating the normal form, and crashing for this trivial
reason or having many command-specific key extraction functions is not
great.
