Update run-test 097-duplicate-method

Runs the test with a precompiled classes.dex and re-enables it.

We need to build a dex file with duplicate methods. We cannot do that
with Jack (this is invalid) or smali (it does not keep duplicate
methods, only one is in the dex). Therefore, having a precompiled
dex file allows to run the test on whatever toolchain.

In the future, we could update the test if a tool allows to generate
it again.
