Fix #2034
Ref #1997

Closes #1634.

This applies the fix from #1821 to the remaining frontmatter properties that consist of lists.

Ref. https://github.com/tc39/test262/pull/1821/files#r222811633.
Ref. #1817.

This makes it possible to run the script locally even if `TRAVIS_PULL_REQUEST` is not set.

Currently, it results in an error:

tools/scripts/ci_build.sh: line 2: [: !=: unary operator expected

Update the lint.py script to work with pip 10+ as pip.req was moved to
pip._internal.req in version 10 onwards and the existing code only works
on versions of pip under or equal to 9.0.3

The document fragments used by the ECMAScript specification do not
conform to any particular pattern beyond the grammar defined by the URL
standard [1]. Relax the linting rule to enforce a simplified version of
that grammar.

Early errors may result from parsing the source text of a test file, but
they may also result from parsing some other source text as referenced
through the ES2015 module syntax. The latter form of early error is not
necessarily detectable by ECMAScript parsers, however. Because of this,
the label "early" is not sufficiently precise for all Test262 consumers
to correctly interpret all tests.

Update the "phase" name of "early" to "parse" for all those negative
tests that describe errors resulting from parsing of the file's source
text directly. A forthcoming commit will update the remaining tests to
use a "phase" name that is more specific to module resolution.
