Allow multiple operators in Where class for each property (#95)

# Description

This PR addresses an issue where the Where class in Neogma was not
allowing multiple operators per property. This change fixes that
omission, enabling the use of multiple operators for each property in
the Where class.

## Type of change
- [X] Bug fix (non-breaking change which fixes an issue)

# How Has This Been Tested?

To verify these changes, I performed the following tests:

- [X] Test for adding two operators to a property

**Test Configuration**:

- SDK: Jest
- Software version: 26
- Toolchain: super-test
