Search doesn't respect pagination

[wtain]

Describe the bug
When searching for a specific artist by name it currently requests 3 results per page per section (default value), not iterating over the next pages.
In this example it happens that the artist of interest comes on the second page, despite full name match, and returns a different artist ("BiC Fizzle"):

genius = Genius("<TOKEN HERE>")
artist = genius.search_artist("Norther", allow_name_change=False)
