Fix parameter resolving issues with procedure calls when auto_explain is enabled.

[emelsimsek]

There are two ways to generate explain resullts:

1. Run the EXPLAIN command with query
2. Turn on auto_explain, to quitely explain queries in the logs.

Citus follows different code paths in those two cases.

It runs out that auto_explain code path cannot handle parameters to procedures when explaining the procedure calls.

I am not highly confident in this change, expecially the part where I had to skip parameters with type 0, to make the code work, but the solution should be similar to this.
