Explicitly Deselect Unselected Fields

[RushiT0122]

Description of change

TDL-26872: Fixes the extraction of unselected fields for all streams by explicitly deselecting fields in the catalog metadata.

Manual QA steps

Existing connections:

Without making any changes in settings,

1. App should have new select_fields_by_default checkbox checked by default
2. Orchestrator should not write new property select_fields_by_default in tap config
3. Tap extracts newly discovred fields

After unhecking the select_fields_by_default

1. App should have new select_fields_by_default uncheckbox checked
2. Tap should read new property equal to `select_fields_by_default==False'
3. Tap doesn't sync extracts newly discovered fields
