Reduce gRPC calls

[germa89]

Maybe we can reduce the number of calls by checking the output after running the command. So if it is empty, then we do the force_output.

And that's the stack I get to wrinqr:
File "/Scratch/vallard/pymapdl/src/ansys/mapdl/core/mapdl_core.py", line 1224, in version
self._version = self.parameters.revision
File "/Scratch/vallard/pymapdl/src/ansys/mapdl/core/parameters.py", line 220, in revision
return float(self._mapdl.get_value("ACTIVE", item1="REV"))
File "/Scratch/vallard/pymapdl/src/ansys/mapdl/core/mapdl_extended.py", line 3157, in get_value
return self._get(
File "/Scratch/vallard/pymapdl/src/ansys/mapdl/core/mapdl_core.py", line 2020, in _get
return self.get(*args, **kwargs)
File "/Scratch/vallard/pymapdl/src/ansys/mapdl/core/mapdl_extended.py", line 2129, in get
with self.force_output:
File "/Scratch/vallard/pymapdl/src/ansys/mapdl/core/mapdl_core.py", line 3100, in enter
if self._parent().wrinqr(1) != 1: # using wrinqr is more reliable than *get
