Fixes "ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()"

Hi @MrQubo, thanks a lot for the contribution!

Is this for this situation where subplot_titles is a numpy array of strings? If so, could you also add a test to packages/python/plotly/plotly/tests/test_core/test_subplots/test_make_subplots.py. You can just copy one of the existing tests that supplies subplot_titles with a list/tuple of string and change that to a numpy array. Thanks!

Thanks for the warming welcome @jonmmease.

I've added test for numpy array as well as tests for ordinary python array and an empty array.

[MrQubo]

I've got bunch of deprecation warning messages when running the tests. Seems like tests need to be updated for version 4.

[MrQubo]

I don't know why CircleCi fails. import numpy is present for example in test_orca/test_image_renderers.py.

Thanks @MrQubo! Once the new numpy test is moved and numpy test dependency changes are reverted (See inline comments) this will be good to go.

Looks like this test is testing subplot titles as a tuple. If that's what you're intending, lets name this test_subplot_titles_tuple.

[MrQubo]

All current tests are using tuples as subplot_titles argument. I thought it would be a good idea to add a test which checks if it works the same with python array.

Looks good. Thanks again @MrQubo!
