REST API devices filter by serial number does not follow the convention for multiple values of the same parameter to resolve by logical 'or' condition

NetBox version

v2.11.12

Python version

3.7

Steps to Reproduce

Issue REST API request to get devices list by two serials (both devices with these serials should exist):
GET api/dcim/devices/?serial=1111&serial=222&brief=1

Expected Behavior

API returns info for two devices, provided we have no duplicate devices with these serial numbers:
{
"count": 2,
"next": null,
"previous": null,
"results": [
{ .... },
{ .... }
]
}

Observed Behavior

API returns info for the device which serial is set as last parameter in GET query
{
"count": 1,
...
}
This is also true for v3.0.11 and v3.1.0
