fix(integ-tests): can't enable lookups when creating an IntegTest (#2…
Browse files Browse the repository at this point in the history 
…2075)

We were not exposing the `enableLookups` property when creating an `IntegTest`. This also updates `integ-runner` to ensure that we are correctly utilizing `enableLooups`. There was an undiscovered (because you couldn't set `enableLookups=true` :) ) bug which set the dummy context on _every_ command (i.e. deploy, destroy) when it should have only been set when synthing the snapshot.
