Fixed suggestions when providing generic type of self as the first parameter

[ChrisUMB]

Previously, there was an issue where if you provided a generic to a type, it would not properly suggest functions.

As you can see, if there is no generic, it properly suggests the function.

However, if there is a generic, it doesn't properly suggest the function.

This commit fixes that.

Furthermore, there was an issue where if you provided a generic type to the first parameter of a non-self function, it would not suggest it. It would suggest it if it wasn't a generic.

This commit also fixes that.

Note: I modified the gradle build file because it wouldn't properly build on my setup for some reason.

@ChrisUMB , is this the same problem?:

With @generic

Without @generic no error:

@ChrisUMB , anyway, can you rebase and solve conflicts, please ?

You can use VSCode to get more powerful generic support.
