improved tests speed

old:

Finished in 7.0 seconds (0.00s async, 7.0s sync)

new:

Finished in 4.9 seconds (2.2s async, 2.7s sync)

updated docs because if you run mix test you get:

== Compilation error in file test/support/contracts.ex ==
** (File.Error) could not read file "tmp/revert_abi.json": no such file or directory
    (elixir 1.18.1) lib/file.ex:385: File.read!/1
    lib/ethers/contract_helpers.ex:406: Ethers.ContractHelpers.do_read_abi/3
    expanding macro: Ethers.Contract.__before_compile__/1
    test/support/contracts.ex:4: Ethers.Contract.Test.RevertContract (module)

elixir_ethers/mix.exs

Lines 124 to 128 in ae8e9ac

	def aliases do
	[
	test_prepare: ["run test/test_prepare.exs"],
	test: ["test_prepare", "test"]
	]

i think its because you cannot alias a builtin mix task (test)

Hey @BlazeWasHere,
Thanks for the PR. It is amazing to speed up the tests.

You can definitely alias built-in mix tasks. The issue you see here is a chicken an egg problem. Our test/support directory which in part of our elixirc_path in tests relies on the ABI generated by prepare_test task. This is problematic since running mix tasks also requires the project to be compiled.

That said, I agree with your solution here.
