Remove dead code blocks that reference non-exposed Tcl commands (e.g.,
sta::find_pi_pole_residue) and delete all write_gate_spice catch blocks
from spice tests since write_gate_spice_cmd SWIG binding is missing,
making all write_gate_spice calls always fail. Added bug report for the
missing binding. All 6531 tests pass.
