False negative for RSpec/Pending in 2.16.0 when reason is some forms of multiline string

[Tabby]

Hi rubocop-rspec team,

When fixing cop violations from the new RSpec/PendingWithoutReason cop, I found that using some forms of multiline string for the pending reason caused the RSpec/Pending cop to no longer trigger for pending specs. For example, these forms were correctly flagged as being pending specs:

it "does do the right thing", pending: "bad spec" do
  ...
end

it "does the right thing", pending: "According to all known laws of aviation, \
                                     there is no way a spec should be able to fly." do
  ...
end

These forms were not:

it "does the right thing", pending: "’Twas brillig, and the slithy specs " \
                                    "Did gyre and gimble in the wabe" do
  ...
end

it "does the right thing", pending: "The sun was shining on the spec,
                                     Shining with all his might" do
  ...
end

it "does the right thing", pending: %(It was the best of specs,
                                     it was the worst of specs) do
  ...
end

A minor issue at worst, but I figured I'd raise it having seen it :)
