Fix nested query building for queries with similar properties in it

Description:

Bugfix for nested queries with similar properties in it, example:

"nested(data.VerticalMeasurements, (VerticalMeasurementID:\"Rotary Table\" AND VerticalMeasurement:(>30)))"

Such queries were transformed into malformed queries like:

"query_string": {
"query": "(data.data.VerticalMeasurements.VerticalMeasurements.VerticalMeasurementID:\"Rotary Table\" AND VerticalMeasurement:(>30))"

Which cause 400(Bad request) responses from elastic.

After fixing queries with similar properties works as expected:

"query_string": {
"query": "(data.VerticalMeasurements.VerticalMeasurementID:\"Rotary Table\" AND data.VerticalMeasurements.VerticalMeasurement:(>30))",

Partially solves the issue: #57 (closed)
