cleos set code/cleos set abi don't appear to work

[spoonincode]

cleos set code and cleos set abi don't seem to work on main, and I'm suspicious they haven't worked in a long time.

The problem is contractPath is empty here when doing set code or set abi and, at least on main, this causes std::filesystem::canonical() to throw

leap/programs/cleos/main.cpp

Line 3474 in 1612650

std::filesystem::path cpath = std::filesystem::canonical(std::filesystem::path(contractPath));

This looks to be a straightforward fix; adding a test will take longer than the fix itself.

We need to verify that this was broken prior to 5.0.

I am able to reproduce this problem in 3.2. Will fix it in 3.2 and merge the fix to 4.0, 5.0, and main.

Will create an integration test in 5.0 and main.
