(PDB-5278) Fix group by dotted fact path with forward slash

[austb]

When grouping by a keyword, honeysql will convert the keyword to SQL by calling name on it. But that will not return the entire fact name when there's a forward slash in it because Clojure interprets everything before the forward slash as the "namespace" and everything after as the "name".

=> (name :facts.foo)
"facts.foo"
=> (name :facts.f/oo)
"oo"
=> (namespace :facts.f/oo)
"facts.f"

This commit changes the query engine to use sql raw instead of the keyword to avoid splitting on forward slashes.

I had a look over this PR and tested on PDB-5262 and that case is also resolved.
