Breaks when search results fit in one page

[m-rey]

Traceback (most recent call last):
  File "./immoscraper.py", line 51, in <module>
    page_count = get_page_count(mainpage_result)
  File "./immoscraper.py", line 18, in get_page_count
    .find("select", {"class": "select font-standard"})
AttributeError: 'NoneType' object has no attribute 'find_all'

The script gets the page count from the dropdown menu. When there is no such menu ( because all the results fit in one page), the script fails.
Implementing #1 to manage page traversal should fix this.
