[BUG] using unassigned variable in except block after failed assignment in try

[fabianegli]

Variables with failed assignment in a try block are not available in the corresponding exception.

sdrf-pipelines/sdrf_pipelines/zooma/ols.py

Line 175 in cf2425d

logger.debug('OLS error searching the following term -- %s iteration %s', req.url, retry_num)

The logging here needs to either compose the url separately or use the variables used to compose the url. Or do both.

Wrong reasoning before, but still an issue.
