awslambda module cannot be resolved
**Description:**

The module `ballerinax/awslambda` cannot be resolved when used the pack fetched using the update tool. 
e.g: `ballerina build testMain.bal`

Same file works if I use a pack installed with the installer. 
e.g.: `/Library/Ballerina/ballerina-1.0.3/bin/ballerina build testMain.bal`

See bellow:

Ballerina file:
```ballerina
import ballerinax/awslambda;

@awslambda:Function
public function foo(awslambda:Context ctx, json j) returns json|error {
    return j;
}
```
