Subject: [PATCH] Changed age_id, age_start_id and age_end_id function
 signatures to IMMUTABLE (#405)

* Changed some function signatures to IMMUTABLE

Changed age_id(agtype), age_start_id(agtype) and age_end_id(agtype) from STABLE to IMMUTABLE.

* Revert "Changed some function signatures to IMMUTABLE"

This reverts commit 92ac40d15f3eb90812323370bf1be23e7526e623.

* Changed age_id signature to IMMUTABLE

* Function signature was changed from STABLE to IMMUTABLE;
* Function receives a vertex or edge container (or null), and analyze its contents to return the "id" stored in said container;
* As it acts only on its arguments, it will always return the same result, given the same arguments, even across multiple SQL statements, being classified as IMMUTABLE function.

* Changed age_start_id signature to IMMUTABLE

* Function signature was changed from STABLE to IMMUTABLE;
* Function receives an edge container (or null), and analyze its contents to return the "start_id" stored in said container;
* As it acts only on its arguments, it will always return the same result, given the same arguments, even across multiple SQL statements, being classified as IMMUTABLE function.

* Changed age_end_id signature to IMMUTABLE

* Function signature was changed from STABLE to IMMUTABLE;
* Function receives an edge container (or null), and analyze its contents to return the "end_id" stored in said container;
* As it acts only on its arguments, it will always return the same result, given the same arguments, even across multiple SQL statements, being classified as IMMUTABLE function.
