Setting range broken for dates

[jsignell]

On latest master I am getting a new failure when trying to set the range on time dimensions.

import numpy as np
import pandas as pd
import holoviews as hv

hv.extension('bokeh')

df = pd.DataFrame({
    'x': pd.date_range('2017', '2018', periods=100), 
    'y': np.sin(np.linspace(0, 2*np.pi, 100))
})
hv.Curve(df).redim.range(x=(pd.Timestamp('2017-05'),pd.Timestamp('2017-09')))

error output:

/Users/jsignell/holoviews/holoviews/core/util.py in dimension_range(lower, upper, hard_range, soft_range, padding, log)
    883     lower, upper = max_range([(lower, upper), soft_range])
    884     dmin, dmax = hard_range
--> 885     lower = lower if dmin is None or not np.isfinite(dmin) else dmin
    886     upper = upper if dmax is None or not np.isfinite(dmax) else dmax
    887     return lower, upper

TypeError: ufunc 'isfinite' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

Thanks, we wrote our own isfinite implementation which also lives in core/util.py for precisely this reason but it seems its not used consistently throughout. Should probably grep for np.isfinite and replace it whereever it makes sense.

Fixed in #3045
