camelCased property not properly serialized

[nilswieber]

Describe the bug
An object with a camelCased property, which starts with a single lowercase character isn't properly serialized.

To Reproduce

fun main(args: Array<String>) {
    val mapper = jacksonObjectMapper()

    val serialized = mapper.writeValueAsString(Test())
    println(serialized)
    val deserialized = mapper.readValue<Test>(serialized)
}

class Test {
    val cCase = 1
}

Expected behavior
The property should be correctly serialized as cCase but it is serialized as ccase.

So the provided code snippet prints the string {"ccase":1} instead of {"cCase":1}

Because of this behavior the deserialization fails with the following error:

Exception in thread "main" com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "ccase" (class de.nilswieber.Test), not marked as ignorable (0 known properties: ])
 at [Source: (String)"{"ccase":1}"; line: 1, column: 11] (through reference chain: de.nilswieber.Test["ccase"])

Versions
Kotlin:
Jackson-module-kotlin: 2.13.3
Jackson-databind: 2.13.3

Additional context
This issue is likely related to #172 and #173

[nilswieber]

One workaround would be to annotate the property with @get:JvmName("getcCase") like so:

class Test {
    @get:JvmName("getcCase")
    val cCase = 1
}

This causes Jackson to recognize the field in the correct way.

@nilswieber Or @JsonProperty("cCase")

The issue of property names in the serialization result differing from the definition in Kotlin will be addressed in #630.
