[PATCH 1/2] t1450: robustify `remove_object()`

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

This function can be simplified by using the `test_oid_to_path()`
helper, which incidentally also makes it more robust by not relying on
the exact file system layout of the loose object files.

While at it, do not define those functions in a test case, it buys us
nothing.
