Hetergenous map is sticking when expected behavior would be to remove

When applying a wind_data object to an FlorisModel that doesn't contain a HeterogeneousMap, after having applied one that does, it appears the HeterogeneousMap is still there

How to reproduce

Add this code as a file in examples:

from floris import (
    FlorisModel,
    TimeSeries,
    HeterogeneousMap
)
import numpy as np

# Create a FlorisModel instance with simple derating
fmodel = FlorisModel("inputs/emgauss.yaml")

# make a time series of without het
time_series = TimeSeries(
    wind_speeds=np.array([8.0]), wind_directions=0.0, turbulence_intensities=0.06
)

# Make a second time series with a het map
het_map = HeterogeneousMap(
    wind_directions=np.array([0.0]),
    x = [-100, -100, 126*7, 126*7],
    y = [-500, 500, -500, 500],
    speed_multipliers = [[1, 1,2, 2]]
)

time_series_2 = TimeSeries(
    wind_speeds=np.array([8.0]), wind_directions=0.0, turbulence_intensities=0.06, heterogeneous_map=het_map
)

# Run without het
fmodel.set(layout_x=[10.0, 126 * 5], layout_y=[0.0, 0.0], wind_data=time_series)
fmodel.run()
print(fmodel.get_turbine_powers())

# Run with het
fmodel.set(wind_data=time_series_2)
fmodel.run()
print(fmodel.get_turbine_powers())

# Now without again
fmodel.set(layout_x=[10.0, 126 * 5], layout_y=[0.0, 0.0], wind_data=time_series)
fmodel.run()
print(fmodel.get_turbine_powers())

Relevant output

The expected output is:

[[1753954.45917917 1753954.45917917]]
[[2422719.54860612 5000000.        ]]
[[1753954.45917917 1753954.45917917]]

However the current output is:

[[1753954.45917917 1753954.45917917]]
[[2422719.54860612 5000000.        ]]
[[2422719.54860612 5000000.        ]]
