test_alice_locks_tokens & test_velock_whitelisted are failing

[trentmc]

NOTE: so that CI is clean, these tests are skipped until this issue gets fixed. Via commit https://github.com/oceanprotocol/df-py/commit/48de5ee2b20143f6edc6f1b7139fda105235862e

How to reproduce

They showed up in CI on about May 12

• Here's the log.
• and again on May 16, see comments below

Yet all tests passed between then! So it's sporadic.

Failure was either one-time or sporadic. Un-skipped, move on

[trentmc]

It's still happening :(

• Here's a recent log where both failed
• Here's another recent log where one failed
