page list reset select2 multi-selected values.

[a31amit]

Environment

• Python version: 3.7
• NetBox version: 2.5.10

Paging results and changing the list from 50 to more devices resets back all search results and using last value by alphabet to search.

It seems like it is affecting to all multiple select options such as site, tenant, model.

Steps to Reproduce

1. Make sure you have default devices show as 50 in dcim/devices and have more than 50 devices.
2. filter devices with any of multi-select fields such as site, tenants, manufacture, at-least 2 values in the same field.
3. change page list size from 50 to 100.
4. It displays results for only for one value. last value in alphabet order always.
5. search boxes also show values for only 1 item rather all those items

Expected Behavior

It should show results from both or all items used in the filter.

Observed Behavior

It displays results for only for one value. last value in alphabet order always.
Hence page list & multi-select not showing all the results.
