Fix array API test failure caused by issue reported in gh-1512

[ndgrigorian]

This pull request adjusts dpt.asarray such that the dtype argument is passed to np.asarray call when called with a Python scalar as input

This guarantees the expected OverflowError is thrown.

Additionally, this PR adds tests for this behavior, for copy=False errors to test_tensor_asarray, and removes a superfluous NotImplementedError for Python sequences from asarray.

Closes gh-1512
