Loader should log ImportError without traceback

[Ryan J Ollos]

Discussed in comment:7:ticket:12282 and the comments that follow, setuptools is improperly raising an ImportError since 20.8.1 when an extras package is not found. Tracebacks are appearing in the log. Instead, we'll log the exception with a message at ERROR level.

Ticket moved forward so that 1.0.13 can be released.

Fixed in [15237] and merged in [15238-15239].
