Squash redundant string concatenations introduced by google-java-format

Reformatting the code with google-java-format tool in change Id5f3c6de9
resulted in wrapped lines being unwrapped to the new 100 columns limit.

In cases where the wrapped line was wrapped on a string concatenation,
the resulting long line now includes redundant concatenations. See the
upstream issue [1] for an example of this.

Squash the redundant concatenations with:

  git ls-files | grep java$ | xargs sed -i '' 's/" + "//g'

(note: this also resulted in a couple of unwanted changes; those are
manually undone.)
