toggle / untoggle of area picker yield different results

[jhpoelen]

as observed by @jhammock
steps to reproduce:

1. go to http://globalbioticinteractions.org/browse
2. wait for data to load, observe total number of interactions in table view
3. toggle area picker on
4. wait for data to load, observe total number of interactions in table view
5. toggle area picker off
6. wait for data to load, observe total number of interactions in table view

expected:
interaction count for step 2. is the same as count for step 6.

actual:
interaction count for step 2. is 1828 and for step 6 is 952.

suggestion:
it seems that on toggling the area selector off, only the first page of the interaction data is loaded - the second page is not requested.
