Adding aliased import when namespace is already required without alias duplicates

[cursive-ide]

e.g. if this is already present:

[lambda.dynamo :refer [->attr ->item ->stack-table from-item]]

requiring via: (dyn|) using autocomplete will result in:

[lambda.dynamo :as dynamo]
[lambda.dynamo :refer [->attr ->item ->stack-table from-item]]
