• Removed event_sources.json of the project root（The same file is in lib.）
• Removed unneeded space in lib/main.js

@abetomo I think this change has lead to the following error during deployment using 0.8.14
Error: ENOENT: no such file or directory, open 'event_sources.json'

@limenutt Have you run node-lambda setup ?

[abetomo]

event_sources.json is a file to be installed in the project root of each user.
(It will also be created in node-lambda setup)

That is, it is unnecessary for root of the node-lambda project.

[limenutt]

No I haven't run node_lambda setup with the new version. What happened is that one of my ci tasks failed to build and deploy lambda function because new version has been published with the change. I think that if I understand semver correctly, you should have incremented the minor version of the package with this update, since it could be a breaking change. Patch version updates are reserved for bugfixes only.

I was troubled with the same trouble so I tried opening the following PR.
