Bugfix/stop console errors

[TezzardzGoneWild]

The console has a few errors on profile page load. This removes the errors coming from the below:

• one of the SVGs had multiple properties using dashes instead of camelCase (ex. stroke-width instead of strokeWidth), and React doesn't read these properly. Same with using class instead of using className
• two functions mapping arrays to HTML elements had the key on one of the children instead of the parent -- React wants keys on the topmost element when something is mapped

An additional bug was fixed:

• this.state.alias is mentioned multiple times, but it does exist. This was improperly used causing every tab to have the title hic et nunc - hic et nunc instead of the profile's name (e.g. tezzardz_gone_wild - hic et nunc). This reference has been replaced with this.state.subjkt to fix the bug and other references removed

Several sections of code received some clean up, but no functionality change:

• onReady included a nested if statement that could be expressed using a single if statement
• the nested if statement used for filtering OBJKT sale type within creationsForSale can be expressed with two one-line if statements
• metadata fields are set to null when the state is initialized to give a better indication of what will happen within the component
• instances where getUserMetadata is called wrote to an intermediate variable and had multiple unnecessary if statements where writing null or undefined would have the same outcome
• this.state.copied has been renamed to this.state.discordLinkCopied for clarity
