Execution of grounded space

[Necr0x0Der]

Describe the bug
An attempt to "execute" a space as a function actually leads to it being matched against many queries from stdlib.

To Reproduce

from hyperon import *

class MySpace(AbstractSpace):
    def __init__(self):
        super().__init__()
    def query(self, query_atom):
        print("query is called:", query_atom)
        new_bindings_set = BindingsSet.empty()
        return new_bindings_set
    def execute(self, *atoms, res_typ=AtomType.UNDEFINED):
        print("execute is called", *atoms)

a = G(SpaceRef(MySpace()))
m = MeTTa()
m.evaluate_atom(E(a))

Expected behavior
Nothing is executed or "execute is called" is printed.

Actual behavior

query is called: id
query is called: atom-subst
query is called: if-decons-expr
query is called: if-error
query is called: return-on-error

Additional context
Most likely, the following query is constructed in attempt to execute a space as a function:
(match &self (= (&myspace) $r) $r)
Then, &self is matched against (= (&myspace) $r) $r), and this equality is matched against each equality in &self (and its subspaces such as stdlib). And thus, &myspace receives functional symbols as queries (although it is not precisely clear why non-zero arity functional symbols appear here).
Nothing too bad is happening, since E(a) will not be reduced unless these queries will be matched against something in the space. It might not be considered as a bug, because an attempt to construct an equality query (if this is what really happening) is natural.
However, what can be desirable is execute method to be called instead of query. Unfortunately, this is not the case now. Also, adding execute to SpaceRef doesn't help. It's still query, which got called.
Also, if we try executing m.evaluate_atom(E(a, S('A'))), the "parameter" (S('A')) doesn't get into query (and doesn't influence on the result, so what's happening might be somewhat different from just constructing an equality query). Apparently, this situation can be improved.
