startsWith error in Safari 8

[imjared]

using Gatsby v1.0.0
I was unable to locate gatsby-node.js, gatsby-browser.js. package.json is as follows:

Possibly similar to #264, we're seeing an issue in Safari 8 when loading config.toml in production:

TypeError: undefined is not a function (evaluating 'o.startsWith("/")'). The trace only shows a line in config.toml but the error doesn't really seem related to the output.

The error output is minified so it's not the most helpful but I think it traces back to these lines

Maybe we can change that instance to use the Lodash variation _.startsWith that's used elsewhere?

Hmm... bummer this got in — it's startsWith is barely supported... I'll fix it right away and make a new release. Thanks for bring it to our attention.

Published 0.12.14 with the fix. Run npm install --save gatsby@latest to get it.
