Frontend/fix tests

[HiruNya]

Description

Tests were left broken and uncompilable, this change allows the compilation of these files and also fixes the large majority of tests, leaving only the ones in ProductDetails component to fail.

More work will be needed to fix the ProductDetails component tests.

How has this been tested?
