Return error message to client upon providing incorrect method parameters

[Eligioo]

Instead of always returning Expected an object for the request parameters statically to the client when incorrect method parameters are provided, return the serde_json error.

Fixes nimiq/core-rs-albatross#3167

Examples:
Input

...
"params": [
	"NQ57 M1NT JRQA FGD2 HX1P FN2G 611P JNAE K7HN",
	"",
	-5
]

Output

...
"error": {
        ...
	"data": "invalid value: integer `-5`, expected u64"
}
...
