Processor is exited after non_interactive block when using Corba

Description of the bug

When using Corba, the current processor is preserved when entering a non_interactive block, but is not preserved when exiting the block, as if non_interactive is silently appending a FINISH command. This is both unexpected and differs from gRPC, which preserves the current processor throughout. This leads to confusing instances of the [command] is not a recognized BEGIN command... error.

Steps To Reproduce

from ansys.mapdl.core import launch_mapdl

mapdl = launch_mapdl(mode="corba")

mapdl.prep7()
print(mapdl.parameters.routine)
with mapdl.non_interactive:
    mapdl.n(1)
print(mapdl.parameters.routine)

This code outputs

PREP7
Begin level

However, this code behaves as expected when run through gRPC (launch_mapdl(mode="grpc")), outputting

@mikerife, could you please attempt to reproduce this error Windows?

[mikerife]

Hi @akaszynski I am unable to test this - MAPDL seems to start but I get the following message:

MapdlRuntimeError: Unable to connect to APDL server

And there is something odd (to me) with the MAPDL processes that started up - two instances of ansys222.exe are running (one w/ -aas flag and one without, but with a -rcp flag and value shared with the ansys.exe instance.

I've got another windows machine, debugging once #1378 is done.

Closing issue because #2517

Please @rileychall use the gRPC interface.
