Bugfix: client batch retrieval without results

[esoteric-ephemera]

• Fixing bugs in client which would lead to infinite recursion in retrieving no results:

from mp_api.client import MPRester

with MPRester() as mpr:
   mpr.materials.summary.search(material_ids=[f"mp-{idx+1}" for idx in range(100)],deprecated = True)

will infinitely recur because the client will try to recursively batch any requests that return 0 results

If an input query is malformed and the client "silently ignores" such a malformed query, we should be solving that by correctly formatting the query and not relying on batching to solve it

• Remove progress bars when results are empty
• Ensure that the batch size is actually the maximum batch size set in the client (100) and not 10
