fix: ignore package json on 6.5.x (#728)

The error in #674 is caused by a change of the package.json file during the build, which triggers some code path that is valid in WatchCompilerHostOfConfigFile but not in WatchCompilerHostOfFilesAndCompilerOptions that this plugin uses (because of the configOverwrite option). This commit ignores the package.json file in watcher as a work-around.
