Blob.lazy adds a blob to a batch to load at a later point, using the
BatchLoader library. Whenever any lazy blob's attributes are accessed,
all lazy blobs requested to that point will be loaded.

BatchLoader, the library we use for this, should only request items in a
batch once. That is, if we have these batches:

1. a, b, c
2. d, e, f

Then a, b, and c should only be requested in the first batch. But if you
modify the list of items in the batch, then the second batch will
request a, b, c, d, e, f, which is almost certainly not what we want!

https://github.com/exAspArk/batch-loader/issues/44 is the upstream issue
for this, but we can also solve this in our application by not modifying
the arguments we're using inside a BatchLoader batch.

[CE] Use presenter for labels in UI

See merge request gitlab-org/gitlab-ce!27374

When rendering a label we want to check 'scoped_label' feature
availability on a project/group where label is being used. For
this reason a label presenter is used in UI and information about
context project/group is passed to this presenter.
