Android d.ts generator fails to create typings for nested data class

[CatchABus]

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 8.5
• Cross-platform modules: 8.5.0
• Android Runtime: 8.5.0
• Android d.ts Generator : 3.0.0
• iOS Runtime (if applicable): 8.5.1
• Plugin(s):

Describe the bug
It seems Android d.ts generator has trouble generating types for data classes declared inside functions.
Generator log output:

Android d.ts Generator Version : 3.0.0
ignoring definitions in missing dependency: android.text.TextWatcher
ignoring definitions in missing dependency: android.view.View$OnFocusChangeListener
Generation of definitions took 712ms.
Typings have been generated in the following directory: ./typings

To Reproduce
This is the kotlin function with class declaration: https://github.com/RedMadRobot/input-mask-android/blob/eee78324eb4cdb4faab3248ef646d5750507b598/inputmask/src/main/kotlin/com/redmadrobot/inputmask/MaskedTextChangedListener.kt#L294

These are the typings generated, you will notice a brace is missing on module pickMask:

export module MaskedTextChangedListener {
	export module pickMask {
	export module ValueListener {
		export class MaskAffinity {
			public static class: java.lang.Class<com.redmadrobot.inputmask.MaskedTextChangedListener.pickMask.MaskAffinity>;
			public component1(): com.redmadrobot.inputmask.helper.Mask;
			public getAffinity(): number;
			public component2(): number;
			public copy(param0: com.redmadrobot.inputmask.helper.Mask, param1: number): com.redmadrobot.inputmask.MaskedTextChangedListener.pickMask.MaskAffinity;
			public hashCode(): number;
			public equals(param0: any): boolean;
			public getMask(): com.redmadrobot.inputmask.helper.Mask;
			public toString(): string;
			public constructor(param0: com.redmadrobot.inputmask.helper.Mask, param1: number);
		}
	}
}

Expected behavior
Typings should be generated without problems.
