Fix casing search issue - v2 patch

[EvilDrPurple]

Fixes

• v1 quicksearch string matching bug data-sources-app#346

Description

• The quick search terms were previously case sensitive, causing some results to be excluded
• Removes .title() function that was previously applied to the search terms
• Changes the SQL query from LIKE to ILIKE (case-insensitive LIKE)
• ILIKE is a PSQL keyword similar to using UPPER() or LOWER() for case insensitive matching in other SQL versions. Read more about it here: https://www.postgresql.org/docs/current/functions-matching.html#FUNCTIONS-LIKE

Testing

• Checkout the branch
• Setup testing environment like normal
• Search using terms outlined in issue 346 and confirm the results are now returned properly

@EvilDrPurple Accidentally merged this!

Functionally, I have no issue with this. However, because it's occurring at the same time as the database client updates, I'd like to request that this instead be a PR into the relevant database client code instead, so as to avoid painful code confusion later on.

In essence, this means either making this a PR into the mc_issue_337_create_database_client branch, or waiting until that's merged into dev and then recreating this PR for that.

@maxachis ah yeah I was actually thinking about that, I can probably just do the same and merge into the other branch real quick
