[FEATURE] Move fetch data to created()

[davidjumani]

Move fetchData to created from mounted to reduce wait time for api calls since the data has been created but the page has not yet been rendered

@davidjumani is that a critical issue, should we do it for 1.0 or 1.1?

It's an improvement, can be done as part of 1.1
