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>

In Rails 5.0 `assert_template` and `assigns()` have been extracted to
the `rails-controller-testing` gem.

This commit adds this gem for rails5.
1. Synchronize used version of `parser` gem for both versions of rails: 4 and 5.
2. Fix broken CI pipelines for rails5 branches.
The 2.5.0.4 version is removed from rubygems, so it's skipped.
