Issue Description:

When using prioritizeKeepingFunctionOutputTogether in release configuration, any init with a parameter is split onto multiple lines, even if it fits within the max line length without line breaks.

Example:

Given this file:

struct Foo {
    init() {
        print("This one is fine")
    }

    init(a: String) {
        print("This one is not")
    }

    init(a: String, b: String) {
        print("This one is not")
    }

    func foo(a: String) {
        print("This one is fine")
    }
}

When using prioritizeKeepingFunctionOutputTogether, formatting results in the following output:

struct Foo {
    init() {
        print("This one is fine")
    }

    init(
        a: String
    ) {
        print("This one is not")
    }

    init(
        a: String, b: String
    ) {
        print("This one is not")
    }

    func foo(a: String) {
        print("This one is fine")
    }
}

Note that this only occurs with init, not regular func, as the example shows.

This is potentially related to SR-13049. When I try the above with a debug configuration, swift-format crashes with SwiftFormatPrettyPrint/PrettyPrint.swift:675: Assertion failed: Too many unresolved delmiter token lengths.
