Use safe repr if ArraySchema was not properly constructed

[nguyenv]

• We cannot rely solely on checking if the context exists for the ArraySchema. We call the parent lt.ArraySchema constructor at the beginning of __init__ which does set a valid context and creates the Pybind11 object. Then we set the other schema properties onto that object. If any of the other properties the user passed in are invalid (like the cell_order or tile_order), then simply checking the existence of a context does not work. Fortunately with the ArraySchema, there is an lt.ArraySchema._check to ensure if it a properly constructor schema
• I am not sure what happened, but the safe reprs which were added in Use Safe repr If Parent Pybind11 Constructor Fails #1545 all disappeared. I'm assuming a PR was not merged correctly after Use Safe repr If Parent Pybind11 Constructor Fails #1545, but they have now been restored
