StringParameter.valueFromLookup doesnt work as expected on first synth

[amwill04]

Using StringParameter.valueFromLookUp doesn't work as you might expect - on the first run at least when the context has no value.

link to reference doc page: https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-ssm.StringParameter.html

Given the following:

const value = StringParameter.valueFromLookup(...)

// you are unable to run any code against it e.g.

if (value === 'foo') {
 // do something
}

on the first synth (and any subsequent refreshes) the value will have the string dummy-value..., or something to that effect.

Receiving the value at synth rather than deployment you would expect the value to be resolved and therefore available.
