environment specific event handlers only work when method is also specified

[sandros94]

Environment

Node 20.18.0
Nitro 2.10.2

Reproduction

Create the following files:

• routes/foo.get.dev.ts
• routes/bar.dev.ts
• routes/[id].dev.ts

Describe the bug

The current implementation checks for an environment specific suffix only when the related method is also specified. This results in the following outcomes:

• routes/foo.get.dev.ts correctly doesn't get bundled into production.
• routes/bar.dev.ts erroneously gets bundled into production.
• if we check event.context.params for routes/[id].dev.ts we get { 'id.dev': 'value' } instead of { 'id': 'value' }.
