API mep.get property "expandUrls" works properly only if selectSelements: ["elements"] is requested. Otherwise macros that takes values from "elements" are not resolved.

Steps to reproduce:
1) Create a map and add map trigger element.
2) Create a map element URL that contains {TRIGGER.ID} macros.
3) Make following API map.get request:

{
 "output": [],
 "expandUrls": "true",
 "selectSelements": [
 "urls", "elements"
 ],
 "sysmapids": "101"
}

Result:
Map element contains resolved macros value in URL.

Now, make another API map.get request:

{
 "output": [],
 "expandUrls": "true",
 "selectSelements": [
 "urls"
 ],
 "sysmapids": "101"
}

Result:
Macros is not resolved in element URL.
