Make sure no member with an e-mail address exists: for the start of a scenario that creates one and for cleaning up after it. It asks the Admin API with the session of the browser and passes when there is nothing to delete.
Examples
Given there is no member with the email "suite.member@example.com"
Given there is no member with the email "newcomer@example.com"
And there is no member with the email "another@example.com"
Then there is no member with the email "suite.member@example.com"
Given there is no member with the email "temporary@example.com"
Pattern
Given(/^there is no member with the email "([^"]*)"$/, …)
