query.select() should overwrite previous selection

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure the feature has not already been requested

🚀 Feature Proposal

Calling .select(fields) should set the query selection to fields

Currently there's no way to reset a previous one, example

query.select({ a: 0 });
query.select({ b: 1, c: 1});

then current select is a merge of the 2 (but that'll cause issues of mixed types (0/1))

Motivation

If a .select() is done from a low-level method, as a default selection, we should be able to overwrite it from elsewhere is in codebase

Use query.projection() instead, query.projection() overwrites the existing projection
