Ignore node_modules when looking for PHP code.

Revert part of the changes in 9cefd88.
A configuration this late in the 1.3 release seems a bit redundant.
However, we should ignore node_modules by default as npm is very
unlikely to be installing useful PHP code, and often installs thousands
of files.
