IMessageMetadata->getField()

[Dimitry Sibiryakov]

Hello All,

are getField(), getOwner(), etc, allowed to return nullptr?

The code in Replicator checks for it but code in isql doesn't and may crash
if nullptr is returned.

Can and does return - in an error case.
I checked particular getField(). 3 of 4 times it's used with check for
an error, last use is in printf which checks for NULLs itself.

Errors is a simple case, I mean normally, for example for unnamed parameters
or constructed by the builder when the names are empty or never set.

In the worse case - empty string.
