In-place selections in Syncopy data classes silently wiped by unwrap_select

[dfsp-spirit]

Describe the bug
In-place selections in Syncopy data objects silently wiped by unwrap_select()

To Reproduce
Given a syncopy data object data, (e.g. AnalogData instance) the following should be equivalent:

cfg = get_default_cf() # whatever
selected_trials = [3, 5, 7]

cfg.select = { 'trials': selected_trials }                                  # Select option 1
spy.selectdata(data, trials=selected_trials, inplace=True)  # Select option 2
freqanalysis(cfg, data)

but calling freqanalysis with the data, the 2nd slection is ignored and the function works on all trials.

Expected behavior
The selection gets honored by the cF function/frontend called, and it works on the 3 selected trials only.

Having a selection defined both as an in-place selection in data, and in the cfg, should lead to an error.
