Bug: api-pipedrive-python v1.3 - SearchItems initialization #59

Not sure this is quite the right place, but I was linked to this repo from this pypi package: https://pypi.org/project/api-pipedrive-python/1.3/

Anyway, in the api-pipedrive-python package version 1.3, there's a bug in the init for the SearchItems class.
init calls self.search_term with no arguments, but the search_term method requires a 'term' arg.

This throws an uncaught error.
