Remove unnecessary gemfile (#135)

* Remove unused gemfile and lockfile

* Remove unused stuff from Gemfile

* Use https source to prevent bundler warning

```
The git source
`git://github.com/activerecord-hackery/ransack-mongoid.git` uses the
`git` protocol, which transmits data without encryption. Disable this
warning with `bundle config git.allow_insecure true`, or switch to the
`https` protocol to keep your data secure.
```

* Move `pry-rails` to main group

* bundle update

* Fix RSpec deprecation warning

```
Requiring `rspec/autorun` when running RSpec via the `rspec` command is
deprecated. Called from
/path/to/activesupport-5.2.2/lib/active_support/dependencies.rb:291:in
`require'.
```
