Material-table: When using lookup with integer value 0 the filtering returns empty results

[kfirshahar]

Describe the bug
When defining a Material table with column lookup field which defines a key with integer 0 for filtering, the data is not properly filtered and ignores records with integer 0 on the relevant column. When using non-zero number or with the string '0' there is no problem.

To Reproduce
Steps to reproduce the behavior:

1. Define a Material table is it appears in the example in https://mbrn.github.io/material-table/#/docz-examples-06-example-filtering
2. Change the value of birthCity from 63 to 0 in lines 18 and 14, which is mapped to 'Şanlıurfa'
3. Select the filter with option 'Şanlıurfa' on the column Birth Place
4. No records are returned by the filter

Expected behavior
Data records with value 0 in the birthCity field should be seen in the table
