• reports_data_hook_spec.rb: file test that causes the issue.

• Set a breakpoint at line 29 create(model.to_s.underscore.to_sym) in test.
• Debug the test.
• When the process pauses at the breakpoint, click Step Over and the process will pause at keyword end below.
• Go to Interactive Console and type Member.count => the result is 0.
• Type Member.first => the result is nil.

Expected result: Member.count should return 1 and Member.first should return the created member.

• Uncomment line 34 byebug in test.
• Run bundle exec rspec spec/reports_data_hook_spec.rb to start testing.
• When the process pauses at the breakpoint, type Member.count => the result is 0.
