1. Add support for `RAILS5=1|true` for the `bin/spinach` command.
2. Synchronize used spinach versions both for rails4 and rails5.

For rails5 it was accidently used spinach 0.10.1 instead of 0.8.10.
That brought some problems on running spinach tests.

Example of failure message:

NoMethodError: undefined method `line' for #<Spinach::Scenario:0x000000000c86ba80>
Did you mean?  lines

Bit of a cryptic commit title, but our seeding will try to guard against
branchnames being anything but alphanumerical. These charachters we gsub
away but can't have an empty string as replacement.

This change is less efficient, but given that the number of seeded MRs
per project is very limited, this should be ok.

This removes the extra check for project-ids which is not needed at all.
This does not necessarily reduce execution time of the query, but
