Edited link to angular-meteor tutorial

[hongshaoyang]

Previous link to angular-meteor.com tutorial is outdated - tutorial has been replaced and I've replaced the link accordingly.

Hi!
The new link you are proposing is a ionic tutorial.
I think the correct link is: https://angular-meteor.com/tutorials/socially/angular1/search-sort-pagination-and-reactive-vars

I saw the same issue at step 7.
More info at: #141

@pugna23 I think you're right about that link. Thanks to you and @hongshaoyang for mentioning this!
