Removing deprecated array assignment from unrelated testsuite

[tinkerer-red]

Description

Currently the random test suites are dependent on deprecated functionality:

var arr;
arr[i] = val;

This feature is already explicitly being testing in the basic array test suite. If this feature fails having this in an unrelated test suite could cause for undo time spent seeking a problem in unrelated tests. This change only serves the purpose to make debugging slightly easier in the future.

I had already summitted a PR relating to this, but only realized now that I should have made a ticket for this first for discussion. Apologies.
#268

Script Name

BasicRandomTestSuite

Steps To The Task

• Remove arbitrary array declarations from a test suite not intended to test those.
