Allow Active Record 5.2 to be used

[pixeltrix]

Also bump the Ruby versions tested against.

Apart from the rubocop failure it looks like it's failing to install the delayed_job gem because the released version still depends on < 5.2. Hopefully when/if collectiveidea/delayed_job#1023 is merged and released then they'll pass.

Is correct this version? ~> 5.2.0?

[pixeltrix]

Argh so many numbers - will fix

[FanaHOVA]

Is this working for you? It looks like delayed_job still makes the build fail. 5.2.rc2 works fine though.

Bundler could not find compatible versions for gem "activesupport":
  In Gemfile:
    delayed_job_active_record was resolved to 4.1.2, which depends on
      delayed_job (< 5, >= 3.0) was resolved to 3.0.5, which depends on
        activesupport (~> 3.0)

    rails (= 5.2.0) was resolved to 5.2.0, which depends on
      activesupport (= 5.2.0)

@FanaHOVA this pr in delayed_job must be merged before. currently delayed_job depends on activesupport ~> 3.0

[pixeltrix]

@wnm technically it's >= 3.0, < 5.2 which means that it works with 5.2 RC gems but not the final version. 🤦‍♂️

DelayJob pull request is merged into master! Lets update to Rails 5.2 💯

[albus522]

Has a couple of issues but I'll take it from here

[toao]

@albus522 thanks for merging, looking forward to the release once the remaining issues are resolved 👍

[dillonwelch]

Is there a list/issues/PRs for the other items that are needed before this can be bumped on Rubygems?

[albus522]

It is out now
