labelAll ignores value

Type of issue

potential bug

Description

We're setting a label to include/exclude bidders from certain page types. The label is 'sod_true' or 'sod_false'. Bidders (i.e. seedtag) should only be called if the label's value is set to 'sod_true'. Here's the bidder config:

    		bidder: 'seedtag',
                labelAll: ['sod_true'],
    		params: {
          		publisherId: 'xxx',
          		adUnitId: 'yyy',
          		placement: 'inScreen',   
                },

I can see in Prebid's debugging mode that the label is set to 'sod_false'

However I can also see that seedtag is beeing called despite labelAll

Steps to reproduce

Visit https://www.fupa.net/league/bundesliga on a mobile device. The label is logged as:

const labels = getCustomLabels(); console.log('Labels:', labels);

Expected results

seedtag not beeing called when the label is not 'sod_true'

Actual results

seedtag beeing called although labelAll doesn't match the actual provided label

Since version 8, labels require the sizeMapping module. It looks like we fail to mention it in our docs.

There may also be a regression - the sizeMapping module is only activated on setConfig({sizeConfig: ...}) - I think 7 may have allowed just "manual" labeling (I'll investigate further). A dummy setConfig({sizeConfig: []}) may work to activate it.
