Fixes #4521.
When LightGBM's core library finds duplicates provided in params, it emits a warning-level log message and uses the value from the first instance of that parameter encountered while parsing parameters.
The R package doesn't enforce uniqueness of parameter names either, but due to a bug in how it converts an R list of parameters to a string, the warning message generated when duplicate parameters are passed is currently incorrect.
This PR proposes fixing that.
