Exclude the database folder and db.php file when pushing a site

[sejas]

Related issues

• Fixes STU-1009
• Related to Database import fails in Studio during MySQL-to-SQLite migration #2063

Proposed Changes

• Database folder and db.php were included when pushing the whole site after we enabled the selective push. This PR excludes them.
• Also exclude debug.log file
• Add tests to avoid including these files in the future

• Run npm start
• Go to the sync tab and push your Studio site selecting both checkboxes (database and all files and folders)
• Observe that the finder opens a tar.gz
• Unzip the file
• Observe its contents
• Confirm the archive didn't include the database folder nor the db.php file.

The changes look good and I can confirm they fix the issue. 👌🏼 DB-related files are no longer included in the export:

Nice refactor. I find the code more readable now.
