FFaker can generate data that randomly break our test suite. This
simplifies our factories and use sequences which are more predictive.

MySQL could not have support for millisecond precision, depends on the MySQL version
so we just create issues in different seconds in a deterministic way
- Create fewer Issue objects; 2 is as good as 5 for these cases. This
gives us a nice little speed improvement.
- Don't `describe` Symbols.
- Simplify object creation.
- Lessen "mystery guest" antipattern
