Swallow .baseDir.ts temp file deletion error statement

[trentgrover-wf]

Problem

With new task tree implementation, TSC tasks now echo a console error: fs: missing callback Error: ENOENT, unlink '/Volumes/CASE/code/wGulp/examples/browserify/src/.baseDir.ts'

Solution

Multiple tsc tasks can now operate concurrently, so it's possible that another tsc task will have completed and subsequently deleted this temporary .baseDir.ts file before the current tsc task completes. The error pops up when 1 of these tsc tasks finishes and tries to delete the temp file, which no longer exists.

It doesn't adversely affect the tsc task for the .baseDir.ts to be deleted in the middle of its operation (only needs to exist at the beginning of the task), so we can just swallow the error.

Testing (How to +10)

• Tests should pass
• Examples should still work and no longer display the above error in the console output from gulp
