Importing tensorflow breaks unloadSpiceKernels

[Mark2000]

Describe the bug
Importing tensorflow causes the unloadSpiceKernels call in BasicEnvironmentModel to fail.

To Reproduce
Steps to reproduce the behavior:

1. Add import tensorflow as tf to the imports in an example script such as single_sat.py.
2. Run the script.
3. Error on shutdown:

Traceback (most recent call last):
  File "/Users/markstephenson/avslab/bsk_rl/bsk_rl/envs/GeneralSatelliteTasking/simulation/environment.py", line 224, in __del__
  File "/Users/markstephenson/avslab/basilisk/dist3/Basilisk/utilities/simIncludeGravBody.py", line 366, in unloadSpiceKernels
  File "/Users/markstephenson/avslab/basilisk/dist3/Basilisk/simulation/spiceInterface.py", line 245, in unloadSpiceKernel
AttributeError: 'NoneType' object has no attribute 'SpiceInterface_unloadSpiceKernel'

Expected behavior
Shouldn't raise that error. What's even going on!?

Version (please complete the following information):

• Python: 3.10.11
• Basilisk: 2.2.1b0
• Plaform: MacOS 13.3.1(a)

Additional Context
Basilisk's spice example does not display this behavior.
