Search schema "data" -> don't filter tables

You can use this template for reporting bugs.
Feel free to remove parts that are not relevant, or just write something free-form if you prefer.

## What did you do?

- I created a schema `data` with some table on it.
- I searched for `data` on table search input
- When I search for it in the db, it doesn't filter anything. It only highlight some

## What did you expect to happen?

- I expected to see the table with "data" in it, and my schema "data" and the table in it.

## What actually happened?

- When I search for it in the db, it doesn't filter anything. It only highlight some of the table with the keyword "data" and highlight the schema "data", but don't filter other table.

## What software versions are you using?

Postico version:
Version 1.5.3 (4090)

macOS version:
10.14.2

PostgreSQL version:
PostgreSQL 9.6.6 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.3 20140911 (Red Hat 4.8.3-9), 64-bit

Reproduce the table search with a schema named `data` and tables containing and not containing that term, using the reported Postico, macOS, and PostgreSQL versions where possible. Trace the table-search entry point and compare highlighting with filtering; done means matching tables and the `data` schema remain visible while unrelated tables are filtered out.
